The A.O. Smith AO-MF-ADV is an under-the-sink purifier which filters water directly from your existing faucet. This drinking water filter reduces up to 99% of 77 harmful contaminants including chlorine, chloramine, lead, mercury, BPA, PFOA/PFOS and cysts. It also improves the turbidity of the water. The water is filtered by four filtration methods but nothing is added to your water during the filtration process.
